Title: Stop cock
Inventor: HARADA TSUKASA
IPC: F16K1/02
Filed: 1988-08-26
Abstract: PURPOSE:To aim at the compactization and the lower cost and facilitate the maintenance by forming a spring member, for seating a valve body at a valve hole with the stretching force at the open time of a cock, to be interposed between a valve guard and the valve body. CONSTITUTION:When a handle 14 is rotated in the revers direction to the said by a user, a valve guard 5 threadedly moves up, and since a clearance gap is generated between a valve rod 11 and the valve guard 5, a valve body 3 is pressed to up by the water pressure from a water inlet, and the valve body 3 is separated from a valve hole 2 so as to make the open cock condition. Under the open cock condition, when the pressure of the outlet 8 side becomes higher than that of the inlet 7, though the condition becomes possible to generate the back flow, the valve boy 3 is seated on the valve hole 2 by the stretching force of a spring member 6 so as to prevent the back flow. That is, a valve comprising a check valve function adding to the previous stop cock function is formed with one valve body 3 so that the compactization and the lower costization can be aimed.

Title: Glass device and luminaire mounted with it
Inventor: AOKI SHINICHI
IPC: F21V15/00
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent a glass device from becoming fine broken pieces even if it is broken, and to improve heat resistance by arranging transparent elastic body having a prescribed thickness in a close contact state between chemically reinforced glass-made glass panes making a pair. SOLUTION: In a glass device, a transparent elastic body 2 is desirably composed of silicone rubber having a thickness of 0.1 to 20 mm, and is arranged in a close contact state between chemically reinforced glass-made glass 1 making a pair. Thus, when the glass device is used as a part of a luminaire, the glass device does not become fine broken pieces even if it is broken, and heat resistance is also enhanced. Since the silicone rubber is comparatively high in transparency, heat resistance and weatherability, the glass device itself is improved in a similar characteristic. Thus, since there is no need to arrange a protector for protecting the glass panes 1 from a flying object, a quantity of light illuminated from the luminaire is not reduced.

Title: Escape-guiding auxiliary tool containing luminous pigment
Inventor: FUJII FUSHIAKI
IPC: G09F13/20
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To securely guide in an emergency, for example, in the dark during power failure or in smoke caused by an earthquake or a fire, by emitting light continuously during the period enough for sufferers to escape in the dark during power failure caused by an earthquake or a fire. SOLUTION: Escape-guiding auxiliary tools 1 contain a luminous pigment, so they absorb surrounding light usually and they can keep emitting light for a long time in the dark in an emergency. The way how to use effectively the escape-guiding auxiliary tools (eg: arrow type) is to label them on a floor or the like of an evacuation route of many department stores, hospitals, other public facilities or the like. Then, because they contain the luminous pigment, they can keep emitting light even in the dark in case of a power failure or in a room filled with smoke because of an earthquake or a fire in an emergency. Therefore, they are very useful as an initial escape-guiding, and they can play the role of the escape-guide even after other escape-guiding lights become unseen.

Abstract: PURPOSE: To prevent air leakage and backlashes between a female pipe body and a male pipe body and to improve the attachability and detachability of both pipe bodies by disposing an annular sealing member to one of the female pipe body and the male pipe body, forming an annular abutting surface to be abutted to the sealing member on the other and forming a clearance part along a peripheral direction opened in a radial direction on the sealing member. CONSTITUTION: On the inner peripheral surface of the female pipe body 5, a groove part 21 is formed near a part where a tip surface 22 as the abutting surface of the male pipe body 7 is positioned in the state of fitting the male pipe body 7 to the female pipe body 5 of a pair of extension pipes 1 and engaging the locking projection part 14 of a clamp 11 to a locking recessed part 16. On the sealing member 23, the clearance part 24a in an annular recessed groove shape is formed on the inner peripheral side of an annular main body part 24. For the sealing member 23, the outer peripheral side of the main body part 24 is fitted and held to the groove part 21 of the female pipe body 5, the outer peripheral surface of a cylindrical part 25 positioned on the base end side of the female pipe body 5 from the main body part 24 is joined to the inner peripheral surface of the female pipe body 5 and it is fixed to the female pipe body 5. Since the tip surface 22 of the male pipe body 7 is air-tightly abutted to the sealing member 23 of the female pipe body 5, the air leakage from the part between both pipe bodies 5 and 7 and the backlash of the female pipe body 5 and the male pipe body 7 are prevented.
